I've had problems with the MP/VHT turquoise changing to the pukey yellow/green when antifreeze got on it. My 1969 340 was that color from the factory, but that is the last engine I'll paint with that color.

How about 273 red? Put one some black valve covers and stick on some aluminum fins and try to convince everyone it's a 273 HiPo. I've been trying to get HemiFred to paint the Hemi in his S&M Duster with the Phord Blue like Jake used to paint them.
